TOKYO (AP) _ Japan's production of cars, trucks and buses climbed to a record high in July due to strong domestic sales as well as exports, the Japan Automobile Manufacturers Association announced Monday.

JAMA officials said the total production in the month came to about 1.106 million units, up 7.9 percent from a year earlier. It surpassed the previous record of 1.086 million units set in April this year.

Officials said the production increase in July sprang from growing demand both in Japan and overseas markets.

Statistics released last week by Japan's two largest car makers, Toyota Motor Corp. and Nissan Motor Co., indicated that exports were especially brisk in July due to the relaxation of restrictions on passenger car exports to the United States and a demand surge in China in the midst of industrial modernization.

Toyota's exports went up 11.5 percent from a year earlier to 192,434 units, the third-largest on record. Nissan's exports reached a record 147,791 units in July.

Their domestic sales also climbed over the year-earlier levels, though at slower paces.

In July, JAMA officials said, production of medium-sized cars and trucks rose faster than that of small vehicles. Output of medium-sized passenger cars totaled 49,605 units, climbing 31.6 percent from the like year-earlier month, while production of medium-sized trucks jumped 32.0 percent to 113,090 units.

Production of small cars, which constitutes the bulk of the market in Japan, grew 7.1 percent from a year earlier to 617,331 units, while that of small trucks edged up 1.3 percent to 180,667 units.

Bus production went up 39.7 percent from a year earlier to 8,002 units in July.
